DRAW-G EAR FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 447,324, dated March 3, 1891.

Application filed September 20,1890. Serial No. 365,621. (No model.)

draw-gear comprises metal stop-blocks which are secured upon wooden sub-draft-sills, the latter being bolted to the main floor-sills. As

is well-known, standard heights for the floor.

and for the draw-gear have been adopted by the car-builders of this country, to which most cars are conformed. To meet the requirements of these standards these supplemental draft- The weight of a set of these timbers, metal stop-blocks, and bolts is considerable. Besides the objection on account of weight is that of cost and lack of security, as draw-gears of this construction are ditlicult to sustain in position under the shocks and strains of service, and are fre quently stripped from the sills. I have devised a draw-gear which obviates these objections, which is strong, light, and efficient in service, and which is readily conformed to the standards.

My invention consists in a draw-gear whose draft members are bent metal plates adapted to be secured directly to the sides of the main sills and of such depth as to project below said sills, and which are provided in the proj ecting portions with offsets which receive the follower-blocks. These plates are thus made to take the place of the draft-timbers and stop-blocks of the usual draw-gear; but they are adapted to the standard spring-pocket and draw-head. These draft-plates are made from metal in any convenient manner, as by bending, forging, or rolling, but are preferably made from steel plates cut to shape and pressed to form. These plates are secured by their upper margins upon the sides of the main sills by bolts or rivets, and they preferably have' a bearing at their forward ends against the rear sides of the end sill.

In the accompanying drawings, Figure 1 is a side elevation of the draw-gear and drawhead. Fig. 2 is a plan view; Fig. 3, a perspective of one of the plates; and Fig. 4 is an elevation and section on line 4 4: of Fig. 2.

In the construction illustrated in the drawings double sills are employed for the floorframes, said sills being metal channel-beams. Wooden sills may be employed. The members of the double longitudinal sills are marked A A and the members of the end sill B B.

G G represent the draft-plates. Their form is best shown in Fig. 3, and saidplates are duplicates of each other. Each may-have the marginal strengthening-flange c, which also serves for a bolt-flange to abut against the end sill and to sustain the straps D for the follower-blocks.

Each of the plates 0 has the integrallyformed offset portion 0, and when said plates are secured with the openings of the offset portions opposite, a pocket is provided thereby to receive the follower-blocks and spring E, to which the usual draw-head F will be attached.

Plates 0 are apertured along their upper edges, and bolts or rivets G secure them to the sill members. The plates are preferably so placed as to abut at their forward ends against the end sills, and bolts are passed through their flanges c to anchor the plates to the end sills.

By reference to the drawings, Figs. 1 and 4, it will be observed that the-offset portions forming the pocket are formed in the parts of the plates which project below the plane of the bottom of the sills. This construction has many advantages.\' It gives a broad plate upon which the strain is exerted edgewise. It enables the supplemental draft-sills and their fastening-bolts and stop -blocks to be dispensed with and permits a direct connection with the main sills and the location of the draft-bar in conformity to the standard. The structure is capableof sustaining much greater shock than the draw-gears in general use, and is much lighter.

My invention is particularly applicable to metal cars which have not heretofore been provided with a practical draw-gear. Of course the specific form and configuration of parts are not essential, and I do not therefore limit my invention to these details.-

In a pending application, Serial N 0. 357,179, filed August 14, 1890, I have shown and described one form of my invention, and I do IOC not herein intend to claim thepartioularconstrnction described and claimed in said application.

I claim- I11 a (llfL\\- L,G21.1,2L draft-connection comprislng tWo metal plates having integral exten- SIODS adapting" them to be secured to the sides of the longitudinal sill or sills of a car, and

integral portions projecting below the sills and having therein offsets to provide bear- :0 ings for the draw-head connections, substantially as set forth.
